<P>
Determines a true or false value for any Java <code>char</code> value, just as <A HREF="../../../../com/google/common/base/Predicate.html" title="interface in com.google.common.base"><CODE>Predicate</CODE></A> does
 for any <A HREF="http://download.oracle.com/javase/6/docs/api/java/lang/Object.html?is-external=true" title="class or interface in java.lang"><CODE>Object</CODE></A>. Also offers basic text processing methods based on this function.
 Implementations are strongly encouraged to be side-effect-free and immutable.

 <p>Throughout the documentation of this class, the phrase "matching character" is used to mean
 "any character <code>c</code> for which <code>this.matches(c)</code> returns <code>true</code>".

 <p><b>Note:</b> This class deals only with <code>char</code> values; it does not understand
 supplementary Unicode code points in the range <code>0x10000</code> to <code>0x10FFFF</code>. Such logical
 characters are encoded into a <code>String</code> using surrogate pairs, and a <code>CharMatcher</code>
 treats these just as two separate characters.
